Address Codes

Span Codes

The span for each channel is set by loading the desired value into the data registers, then issuing one of the span
commands. The last 4 bits set the span as shown below. The rest of the data should be set to

0

.

Readback Enable

Each time a command is issued to one of Linear Tech LTC-2704 devices, the value of one of the buffers is simultaneously

shifted out of the device. Except when issuing one of the specific readback commands (Ax, Bx, Cx, Dx), the data

returned corresponds to the Readback Pointer from the previous command as shown in the

Command Codes

Table

. The

Readback Enable bit must be set to

1

to read this data.

Note:

If the Readback Enable bit is set to

0

, a read of the DAC data registers will return the last value written to that

register not the Readback value of the actual buffers.
